Chris/Ben,
I wont be able to give you a certain answer but if the information given is anything to go by i would assume the Canadian models get a multi function steering wheel? If so i see no reason why purchasing a MFSW with paddles and bolting it on would not work. Just bare in mind, having access to VCDS/OBD11 will be necessary to clear the fault codes that get thrown up (as you put the steering sensor out of alignment and have to remove the the airbag during the install) But once these are clear everything works as should.
Can one of you throw up a picture of your steering wheel? Just curious if its the same one as over here in the UK.
